[mapserver-users] Changing Scalebar units with Mapscript/3.4

[Mark Giesbrecht]

Hi All,

I'm trying to use PHP/Mapscript 3.4 to change scalebar units
dynamically, using the following:

...PHP code
$gpoMap = ms_newMapObj("reliant_base_test.map");
if (isset($map_scalebar_units))
{
     $gpoMap->scalebar->set("units", $map_scalebar_units);
    //pure shot in the dark, as I don't know of any scalebar method
}


...from mapfile
  SCALEBAR
      STYLE 0 #or 1
      STATUS EMBED
      INTERVALS 6
      COLOR 10 10 10
      OUTLINECOLOR 10 10 10
      UNITS miles
      POSITION LR
      LABEL
         TYPE BITMAP
         ANTIALIAS
         COLOR 15 15 15
         SIZE small
      END
      TRANSPARENT TRUE
    END

I haven't found anything to work; am I at a loss?

Thanks,

Mark
